The horizintal distance travelled t seconds following the kick is
X = 15 cos 35 * t
The vertical height is
Y = 15 sin 35 * t - (g/2) t^2
g = 9.8 m/s^2 is the acceleration of gravity
You should be familiar with these formulas.
Solve the Y equation for the time T when Y = 0. That will tell you how long the ball is in the air. Then use the X equation to find out how far it has travelled during that time T.
